WASH-BOARD.

SPECIFICATION forming part of Letters Patent No. 444,022, dated January6, 1891. Appncfttiumedrlpi18,1890. serinNasLiazo. cromata) To alt whomit may concern.-

Be it known that I, MONTEZUMA SCOTT, of New Brighton, in the county ofBeaver and State of Pennsylvania, have invented a new and usefulImprovement in Wash-Boards, of which the following is a full, clear, andexact description.

The object of my invention is to provide a vitreous-faced Wash-boardwhich shall possess in a high degree qualities of eheapness ofconstruction, durability, efficiency, and cleanliness. I have discoveredthat if instead of making a Wash-board with its rubbing-surface of asingle sheet of corrugated glass or earthenware, as heretofore, it bemade of glass sections or of glazed sections of earthenware tile oflimited size with corrugated faces a strong and durable article is had;and it is in such wash-board that my invention consists.

I am aware that heretofore it has been attempted to make wash-boardswith rubbing faces of a single glazed tile or sheet of glass, but sucharticles were objectionable, because it was practically impossible toprevent the warping of the tile or sheet during its manufacture, so thatthe surface was irregular, and in case of the glass-faced board the sizeof the sheet made it liable to crack when in contact with hot water. Allthese objections are obviated by my invention, since being made insections a rubbing-face of perfect regularity can be had, and when madeof glass its sectional structure prevents it from bein gbroken by suddenexpansion under heat.

The invention is illustrated in the accompanying drawings, in which-Figure l is a plan view of my improved wash-board, and Fig. 2 is avertical section on the line II II of Fig. l.

Like symbols of reference indicate like parts in each.

The wash-board frame is made in the manner illustrated in the drawings,having end pieces 2, side pieces 3, and a supporting back plate 4,forming an inclosure for the glazed rubbing-surface. Thisrubbing-surface is composed of a number of glazed sections 5, which maybe made either of glass or glazedearthenware tile, the faces of whichare corrugated, and the edges are adapted to t neatly against eachother, so as to form a continuous surface. In order to hold the sectionsin place in the frame, I provide the outside edges with projectingintegral tongues 6,

which are adapted to fit in holes in the side and end pieces of theframe. The manner of fitting together the parts of the wash-board willbe readily understood. The sections are placed together on the backboard, the side and end pieces of the frame are secured around them, sothat the tongue 6 shall enter the proper holes, and in order to hold thesections in place with still greater security I may form a nail-hole bynotching the intermediate adjoining corners and may drive a nail throughsaid hole into the back board. The sections are so set relatively toeach other that the corrugations of the laterally-adjoining sectionsshall register, and in order to prevent tearing of the clothes, whichmight result from sharpness of the meeting edges b of the ridges on thetile, I make such edges rounded, as shown in the drawings. The sectionsare also formed at their ends a a, so that the parting between thesections shall be at the base of the ridges, and shall therefore bebelow the surface against which the clothes are rubbed.

It Will be understood that,instead of forming the sectionswith parallelgrooves, as shown in the drawings, the rubbing-faces of the sections maybe formed in the manner of the various styles of washdooards now in use.The raised meeting edges of the section in each case are preferablyrounded. The wash-board so constructed is of great utility, is strongand durable, and the glazed surface thereof makes it cleanly andprevents it from injuring the clothes. The manner which I have shown anddescribed for securing the sections together is of marked benefit, and Idesire to claim' the same specifically7 herein; but it will beunderstood that other securing means may be employed and that I do notlimit to such illustrated means the broad claim of this application,since- Vhat I claim, and desire to secure by Letters Patent, is-

A Wash-board having its rubbing-face composed of a series of corrugatedor roughened vitreous-faced tiles or sections of limited size,substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand this 15th day of April,A. D. 1890.

MONTEZUMA SCOTT.
